Core trick

Vision extracts a schematic PDF into a queryable electrical graph, and the agent answers only by querying that graph, never guessing component references.

Description

Every year, 50 million tons of electronics become waste — not because they can't be repaired, but because board-level expertise is locked in a few hands. Millions of independent repair technicians, from Chennai to Shenzhen to my own workshop in France, fix screens and batteries — but stop at the motherboard. Wrench Board unlocks that last mile. An agent-native diagnostic workbench powered by Claude Opus 4.7: type a device label, and four Claude agents — Scout, Registry, Writers, Auditor — produce a verified repair pack in two minutes. Upload the schematic PDF, and Claude vision compiles it into a queryable electrical graph. Then the agent takes over: it interrogates the graph instead of guessing, pilots the boardview visually, highlights components, draws boot sequences phase by phase, proposes auditable diagnostic protocols with measurement widgets, cites its sources, and never fabricates a reference designator. Across sessions, every finding is mirrored to a per-device Managed Agents memory store for cross-session continuity. Built and dogfooded in my own repair shop. Right-to-repair becomes real when one technician with a multimeter can do what only an OEM service center could do yesterday.
